The minimum roof pitch for shedding snow is around 30 or a 6 12 or 7 12 slope although this is not a definite as the material of your roof the direction of the snow and wind are some factors that can affect whether or not snow will slide as roofs of as little as 10 have been reported to shed snow.
A ratio is the most common way of expressing roof pitch or roof slope but degrees are also possible.
Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10.

We ll be building a 4 12 pitch roof with an 8 span with 1 of overhang.
So if your roof rises 4 inches for every 12 inches of horizontal length then the pitch of your roof is expressed as 4 12.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.
